--- Comment #1 from Jim Wilson <wilson at gcc dot gnu.org> ---
Constant addresses are VOIDmode, and it only accepts Pmode and ptr_mode.  It
should accept VOIDmode too.  For instance cse_lookup_mem does this
  addr_mode = GET_MODE (XEXP (x, 0));
  if (addr_mode == VOIDmode)
    addr_mode = Pmode;

This stems from changes that Alexandre Oliva made.  Adding him to the cc list.
